MIAMI, FLORIDA, A CORPORATION OF FLORIDA COMBINED IRRIGATION AND DRAINAGE PUMP Application led May 31, 1928. Serial No. 281,754.

This invention relates to a combined irrigation and drainage pump.

The object of my invention is the construction of an efficient pump for furnishing a water control system for small units of land enclosed by dikes, the apparatus being used to pump water from a main water control ditch located outside the dike onto the land for irrigation, and, reversed, to pump water from the land into the control ditch for drainage.

Another object of my invention is the construction of a peculiar and eiicient pump which has its discharge point located ona level with the bottom of the ditch, whereby water in the main casing of the pump is never raised an inch more than necessary.

Water is raised in the vertical casing of my apparatus just high enough to cause a flow through the culvert line into the discharge ditch and no more. As water in the discharge ditch rises, the pump automatically lifts the water level in the vertical casing enough to overcome it. This results in a considerable saving in power required to pump a given quantity of water, with no sacrifice of pumping range.

Owing to the reversible feature of my pump, it can be used asadrainage pump by merely changing the twist of the driving belt, which reverses the rotation of the propeller blades and thrusts water down and out of the vertical casing instead of lifting it. Water is thus drawn through the culvert line and forced into the main water control ditch, even though its level be considerably higher than that of water inside the dike.

Further, by reason of my peculiar apparatus, as water is carried through the dike at ditch level, by throwingr oif the drive belt and allowing free rotation of the propeller blades, the pump can be used as a gravity drain with only a nominal loss of eiiiciency.

With the foregoing and-other objects in view, my invention comprises certain novel constructions, combinations and arrange.- ments of parts as will be hereinafter' fully described, illustrated in the accompanying drawings, and more particularly pointed out 50 inthe appended claims.

In the drawings:

Figure 1 is a view in side elevation of an apparatus constructed in accordance with the present invention.

Figure 3 is a sectional view taken on line 3-3, Figure 2, and looking in the direction of the arrows.

Figure 4 is a vertical sectional view taken o0 on line 44, Figure 2, and looking in the direction of the arrows. l

Figure 5 is a top plan view of the pump.

Flgure 6 is a vertical sectional view taken on line 66, Figure 4, and looking in the di- 65 rection of the arrows.

Figure 7 is an enlarged side view taken on line 7 7, Figure 2- and looking in the direction of the arrows..

Figure 8 is a sectional view taken on line 70 8 8, Figure 7, and looking in the directie of the arrows.

Referring to the drawings by numerals, 1 designates the support or framework, comprising the vertical uprights 2 carrying the 75 horizontal beams 3, and the uprights are suitably braced by crossed pieces 4. Suitably braced upon the beams 3 are vertically eX- tendmg uprights 5 that are provided with a cross piece 6, for the purpose hereinafter specified. l

A vertical primary casing 7 is positioned between the uprights 2 of the framework or support l, and this casing is entirely suspended above the bottom ofthemain water control ditch 8 by preferably-apair lof horizontal angle brackets 9.' Eachbracket 9 is L-shape in cross section, Fig.. 4, with the vertical flang'e fixedly secured tothe casing 7, and the horizontal flange notched at 10, in a plufv rality of places, for receiving the vertical up rights 2, as clearly shown in Figure 3. Suit; able fastening means 11 is driven through the vertical flange of each bracketQ into the uprights, whereby the pumpr is" lsecurely suspended upon the framework. The notching. of the angle brackets 9, for receiving the up-"i rights, produces a very eflicient and `durable structure, as all of the uprightsare loc-ked"' together by these metal hor1z0nt`albrackets. 100

. Attached by suitable means to the lower end of casing 7 is a substantially U-shape bracket 12; this bracket serving two functions, to wit: it supports the lower thrust socket collar bearing 13, as well as the horizontal bracket 14, Fig. 2. Fastened to the under face of beam 6 is an upper thrust socket collar bearing 15. The ends of'rotatable shaft 16 are journalled in these collar bearings' 13 and 15. A belt wheel or pulley 17 is securely fastened on shaft 16 with a belt 18 thereon. This belt 18 may be twisted for reversing the movement of the shaft 16 or by removing the belt entirely oft' pulley 17, the shaft may idle.

Propeller blades 19 are fastened to the shaft 16 near bearing 13 and washer 20 is interposed between the upper end of bearing 13 and blades 19. A ring 21, L-shape in cross section, is `permanently fastened in the upper end of the casing 7, and on the horizontal fiange of this angle ring (Fig. 4) is securely fastened the cover plate 22. This cover plate `is welded ,at 23, -to the pipe housing 24 Within which housing is a bronze block or sleeve 25. Hard bronze washers 26 are placed at the ends of housing 24 and sleeve 25 (Fig. 6) and against these washers, on shaft 16 are thrust collars 27, whereby shaft 16 can rotate freelywithin the casing 7, but the casing and its peculiarly constructed head will remain stationary.

,One of the several important features of my improved irrigation and drainage pump is the formation of a culvert-receiving casing 28 at approximately the center of the main casing 7; this horizontal culvert-receiving casing 28 is used as a discharge or suction inlet of the pump, because the inner end of the culvert pipe line 29 extends into the casing 28, so that when water is being pumped 'into the irrigating ditch 30,-the horizontal casing 28 serves as an outlet, whereas when the pump is serving as a drainage apparatus, the casing 28 acts as -a suction or inlet unit, for the water to enter the main casing 7 and pass out through its bottom. It is to be noted that the whole of my pump is suspended clear ofthe ditch, with the lower bearing for the rotary shaft supported upon the depending bracket 12.

. At the outer vend of the culvert pipe line 29, within the irrigation ditch 30 (which may also be a drainage ditch), I preferably place va gate-valve device 31. It will he seen upon referring to Figure 1, that the discharge point of the pump is located on a level with the bottom of the ditch 30: Therefore, water is never raised an inch more than necessary. Further, should the water be raised above the casing 28, there is an expansion chamber formed in the upper part of casing 7, but only in extreme cases is the water raised higher than just sufficient to flow through the culvert line into the dischargev ditch, and no more. As stated before, this results in a Considerwith the bottom of the irrigation or drainage ditch is an important feature of my invention.

A grease cup 32 is connectedto housing. 24 and a second grease cup 33 is fastened on the upper end of grease line or pipe 34. This pipe extends downwardly through horizontal brackets 35'and 14. Then the pipe 34 extends through a horizontal aperture 36 (Fig. 8) and connects to the bearing 13, fastened to the U-v shape bracket 12. By placing a lubricantin grease cup 33, the lower end of the pump will be eiliciently lubricated. Therefore, it will be seen that U-shape bracket 12 very efficiently mounts the lower end of the grease line 34 on the pump, while at the same time supporting the lower end of rotary shaft 16, all free and above the bottom of the main ditch.

As indicated by dotted lines A in Figure 1, it is within the scope of this invention to` extend the culvert pipe lines in opposite directions, so that water'may be discharged into a number of irrigating ditches at preferably the lower part thereof, or equally as well a number of drainage ditches may be drained completely by the water passing from the bottom of the ditch or ditches into the main casing 7, and thence into the main ditch 8.

My pump may be placed in any part of the main ditch for best results, by building the framework so that the pump is suspended entirely thereon, above the bottom of the ditch, with itsY discharge line positioned for supplying water to or draining .water from the bot# tom of each and all irrigating ditches, or drainage ditches with which the pump is connected up, this being accomplished by the peculiar manner hereinbefore described, of

forming the horizontal casing 28 and the y horizontal culvert pipe line 29. y
